I don't think it's related to Deployer, because it's only a wrapper for
deployement, but we will investigate the issue and give us feedback as soon
as possible. It's Holiday here today.

> target/grizzly-comet-chat.war --cometEnabled=true

> The server is taking around 1 GB of heap space on 2000-3000 concurrent
> clients which I feel is a little high.Or is it expected to work like this?
> I used Java VisualVM and took a heap dump. I have attached the screen shots

> In the heap dump I can see a byte[] which itself takes around ~17MB per 100
> connections and remains constant.Can we optimize this some how?

> Below is the attached screen shot of the heap dumps.
